Re: Trace to console

[Jérémie Galarneau]

Hi Chidhu,

LTTng does not support selective output of tracepoints to the console.
The closest thing I can recommend is using the "live" mode locally.

Also, is there a way to redirect all tracepoints to console instead of
selective?

Ok. I will try the live mode. Looks like it will solve the purpose.

Trace to console

[Chidhu R]

[-- Attachment #1.1: Type: text/plain, Size: 429 bytes --]

Hello,

I was looking for a way to trace to console rather than save to disk /
stream. I read about lttng tracef feature. But it does not include the wide
range of benefits brought by tracepoints. So what I want is to use the
tracepoints and trace to console instead. For example, if there are 5
tracepoint events, I want to trace 3 of them to console and let the other
go the disk or whatever. How to achieve this.

Thanks
Chid
